I was using Garmin Fenix 7S for more than 8 months, everything was perfect until suddenly one day it got fully discharged while an activity; after that battery consumption increased massively. After a few painful months of constant watch charging, I've changed them to 7S Pro. Everything was just wonderful until a few days ago again it got fully discharged while the run and now it faces the same problem - the battery has started drain massively without any activities in place. I got them charged yesterday to 95%, after 30 hours it's 65% left, when previously they would use only 5-7% per day or so. Soft restart would not help. In fact, non of the things described on support pages I found wouldn't help. Seems like there is a bug somewhere, due to it happens to me on the second pair of watch already...
